Siemens 6ES7223-1HF22-0XA0 Digital IO Expansion Module

Siemens 6ES7223-1HF22-0XA0 is a SIMATIC S7-200 digital I/O expansion module (EM 223) designed exclusively for S7-22X CPUs, adding four digital inputs and four relay outputs to extend the discrete I/O of older S7-200 controllers. It draws up to 40 mA from the backplane 5 V supply and operates with a 5–30 V DC logic supply. Each relay output can switch up to 230 V AC (with a permissible range up to 250 V AC), while the DC-rated input level is 24 V. Each energized output coil requires about 9 mA, for a total coil current of up to 36 mA when all four outputs are active. This EM 223 module expands the S7-200’s capabilities for simple automation tasks such as machines and conveyors, while maintaining compatibility with the EM 223 electrical interface and the S7-22X CPU family.
